Pets have occasionally inherited vast fortunes, reflecting the deep affection their owners had for them. For instance, Majel Barret-Roddenberry, widow of 'Star Trek' creator Gene Roddenberry, left $3.3 million to her pets in her will. The world's richest dog, Gunther III, inherited $65 million from his owner, the late countess Karlotta Liebenstein, which grew to $375 million through wise investments. The richest cat, Blackie, received $12.5 million from antiques dealer Ben Rea, who left nothing for his family. Other notable pet inheritances include Tommaso, who gained nearly $14 million from Maria Assunta, and Trouble, a Maltese dog who was initially bequeathed $12 million by billionaire Leona Helmsley, later reduced by a judge to $2 million. These stories illustrate the extraordinary lengths to which some owners go to ensure their pets are well taken care of after their passing.
